Could this be the hemi tick?

If it was ticking in operation, then it's hemi tick. If not, it's just a loose roller. Or are you asking if that is the possible cause of most of these hemi ticks? Can't say not, can't say yes, as most of us aren't choosing to take apart the top end when we get ticks. Perhaps that is the next thing we with hemi ticks should be considering. I do see they say lifter failure, but not cam failure, which is what we are most worried about. I'm not sure that alone would eat a cam lob, I think the lifter has to have backward pressure to eat that lob like we see.

Just posting what I came acrossed, a bad lifter before the cam was destroyed and what was discribed as a "tick". I think at some point the roller will start binding up and skiding on the cam lobe or start being offset on the cam lobe and start excellerated wear of the cam lobe. Thought I would post it because most the time we only see pictures (good video of the roller/needle bearings) of destroyed cams and lifters and hard tell what part went bad first.

I'd be curious to know what oil was being run in that Hemi before this lifter was pulled out. I think I'm just gonna open another low risk fund at my brokerage and stash away money for a full cam install kit from Greene as well as the labor should I ever have a cam failure. If I never need it I can roll it into my main long term emergency fund and if I do I'll have the money stashed away for it.
